So, you’re out enjoying a beautiful sunny day, cruising along on your trusty bicycle, when suddenly, disaster strikes! Your bike chain decides to misbehave and disrupt your peaceful ride. But fear not, dear cyclist! In this guide, we’ll walk you through the process of fixing a bike chain in just five easy steps. Before you know it, you’ll be back on the road, pedaling away with a smile on your face.
Understanding Your Bike Chain
Before we delve into the fixing process, it’s essential to understand what a bike chain is and why it’s crucial for your cycling experience. Picture it as the powerhouse of your bicycle, responsible for transferring the energy from your pedaling motion to the wheels, propelling you forward with each revolution. Without a properly functioning chain, your bike would be rendered useless.
Now, let’s take a moment to explore the inner workings of a bike chain. It consists of a series of interlocking metal links that form a continuous loop. These links mesh with the chainrings and cassette on your bike, allowing you to shift gears and maintain a smooth and efficient ride. With regular use, however, your chain can encounter a few hiccups along the way.
Common Problems with Bike Chains
Bike chains are an essential component of a bicycle, but they can experience several problems. Here are some of the most common problems with bike chains and how to fix them:
Jammed Chain: One of the most typical problems with a bike chain is a jammed chain. When the chains get jammed, they make it difficult for the rider to move the bike forward, making it impossible for them to even take their bike to the mechanic. To fix this issue, you can use a chain tool to push out and push in the pins, allowing you to remove or attach links. Fixing a broken chain amounts to removing the broken link and re-attaching the remaining ends1.
Broken Chain: A broken chain can occur due to several reasons, such as poor shifting technique, the chain being too long, or a worn-out chain or rear casters. To fix a broken chain, all you need is a chain tool. These are compact and built into many common multi-tools. You may even have one on your multi-tool that you never even knew what it was for! At home in your garage, it’s possible to repair a chain with just a hammer and pliers, but a chain tool is easier and really the only option on the street2.
Slippery Chain: A slippery chain can occur due to a lack of lubrication. To fix this issue, clean the chain with soap and water, let it dry in the sun, and then apply the drip-on and allow it to set and penetrate overnight. A good rule of thumb is to clean and lube your chain whenever the chain starts squeaking, or if it’s looking gunky. If you’re feeling super-thorough, you can clean and lube your chain every 100-150 miles or once a week if you are riding most days on pavement in dry conditions3.
Skipping Chain: A skipping chain can occur due to a worn-out chain or cogs. If your chain continues to slip, the chain or cogs are probably worn out. Have a local mechanic look at your bike and determine which needs to be replaced. If it’s the chain, you can fix it by removing the broken link and re-attaching the remaining ends4.
Stiff or Misaligned Chain: A stiff or misaligned chain can occur due to poor shifting technique or a bent derailleur hanger. To fix this issue, you can adjust the derailleur or take your bike to a mechanic to fix the bent derailleur hanger1.
